... I sent this a while ago but from my @ethz account: Pavan, Good points. I believe we wanted to include many of them in the errata (which may or may not happen ...). The only thing I disagree to is slide 6. Win_sync really does nothing in the separate case. Your example would work on shared memory if flush issues a memory barrier *and* MPI_Barrier() is an optimization barrier (which is is in C and needs to be ensured in Fortran anyway). But we can discuss next week. Best, Torsten On Sat, Dec 01, 2012 at 08:21:52PM -0600, Pavan Balaji wrote:
